Hi Guys, Bought a used late 2008 Macbook Unibody and have a few questions (NOTE: this is my first mac and new to OSx) 1) How do check the revision of my screen panel? 2) How do I make the dock not always on top? Want my whole browser to take the whole screen 3) Is there a way to change the keyboard for a new one? Also the bottom casing of the unibody? Can it be change to a new one? 4) How to check my disk space? 5) What's the best browser for mac? Firefox or Safari? I might be able to google some of my questions, but since I have a few ??, I'd rather get the answer with people who already has extensive experience with mac. Thank you and any info would be greatly appreciated.
